Eric Milles updated GROOVY-4737:
--------------------------------
Language: groovy
> propertyMissing not called in anonymous or inner classes
> --------------------------------------------------------
>
> Key: GROOVY-4737
> URL: https://issues.apache.org/jira/browse/GROOVY-4737
> Project: Groovy
> Issue Type: Sub-task
> Components: groovy-runtime
> Reporter: Demian Ferreiro
> Priority: Major
> Attachments: Groovy4737.groovy, propertyMissing.groovy
>
>
> The next code snippet illustrates the problem:
> {code}
> class Foo {
> def propertyMissing(String name) { "missing $name" }
> def getBar() { "bar" }
> }
> def f = new Foo()
> assert f.bar == "bar"
> assert f.baz == "missing baz" // porpertyMissing is called.
> def f2 = new Foo() {
> def getFoobar() { "foobar" }
> }
> assert f2.foobar == "foobar" // This works ok.
> assert f2.bar == "bar" // This works too.
> assert f2.baz == "missing baz" // This breaks :(
> {code}
> The last line [throws a MissingFieldException|http://ideone.com/tJZ6l].
> If instead of using an anonymous class for the f2 variable a normal class
> that extends Foo is used, the propertyMissing method is called correctly.
> No inheritance is required. If an anonymous class is defined as:
> {code}
> def obj = new Object() {
> def propertyMissing(String name) { "this is also ignored" }
> }
> obj.foo
> {code}
> The MissingFieldException is also thrown.
> This also happens with inner classes. I think this behavior is unexpected,
> because one would think that the only difference between an inner class and a
> normal one is that an instance on the first one can access the fields and
> methods of it's enclosing object.
